Behat works fine but PhantomJS fails on dropdown menu when trying to click

问题

Gherkin below works fine with behat but when I use PhantomJS I get error on When I follow "Profile" line below:

Note: The element is a dropdown menu from bootstrap so it toggles after click.

Error:

Exception thrown by (//html/.//a[./@href][(((./@id = 'Profile' or contains(normalize-space(string(.)), 'Profile')) or contains(./@title, 'Profile') or contains(./@rel, 'Profile')) or .//img[contains(./@alt, 'Profile')])] | .//*[./@role = 'link'][((./@id = 'Profile' or contains(./@value, 'Profile')) or contains(./@title, 'Profile') or contains(normalize-space(string(.)), 'Profile'))])[1]

Gherkin:

When I follow "Profile"
And I follow "Edit"

HTML:

<ul class="nav navbar-nav navbar-right">
    <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Profile <span class="caret"></span></a>
        <ul class="dropdown-menu" role="menu">
            <li><a href="#">Show</a></li>
            <li><a href="#">Edit</a></li>
        </ul>
    </li>
</ul>

回答1:

I've discovered why and solved with a small fix as shown below.

When using Bootstrap, the menus get squashed down and only an icon appears to represent the same menu which is the normal behaviour for responsive design. All fine for now but when PhantomJS is run, it cannot find the text it is looking for. e.g. "Profile" menu in my case.

Original state of the menu, which always works fine:

After squashed down version which causes PhantomJS to fail:

SOLUTION:

Just set the window size to something bigger so that the menu doesn't get squashed down when testing. You can change the screen size from 1024X768 to something else as you wish.

#symfony/src/Site/CommonBundle/Features/Context/FeatureContext.php

/**
 * @BeforeStep
 */
public function beforeStep()
{
    $this->getSession()->resizeWindow(1024, 768, 'current');
}
